          GetWindowText(hEdit, t, sizeof(t));
          MessageBox(hwnd, t, " ", MB_OK);
          r = 0;
        while(r <= sizeof(t))
        {
            if(isascii(arr[r]) == 0)
            break;
            arr[r] = GetLetterValue(&t[r]);
            itoa(arr[r], temp, 10);
            MessageBox(0, temp, "Error", MB_OK);

            break;

Thats my hotkey function to fill t with the text in hEdit and then get the number rep of each letter.  The problem is its only printing the first 3 letters.  So say i put abcde in the hEdit.  it will Message out 1, 2, 3 then stop...any ideas?
